Combining with our previous measurement of BD0→K-e+νe, the ratio of the two branching fractions is determined to be BD0→K-μ+νμ/BD0→K-e+νe=0.974±0.007stat±0.012syst, which agrees with the theoretical expectation of lepton flavor universality within the uncertainty. A study of the ratio of the two branching fractions in different four-momentum transfer regions is also performed, and no evidence for lepton flavor universality violation is found with current statistics.
